GRINDING APPARATUS

摘要

PURPOSE: A grinding device is provided to prevent interference in a turning motion and to minimize the amount of a grinding stone from being received in a receiving space. CONSTITUTION: A grinding device(100) comprises a frame(110), a plurality of shafts(120), a turning drive unit(130), and a grinding tub(140). The shafts rotate around an axis along each extension direction and are aligned in parallel to form one row. The turning drive unit is installed in the frame to be interlocked to each shaft. The turning drive unit rotates each shaft between the first and second positions. The grinding tub is extended along an alignment direction. Grindstones which are rubbing against an object and installed in the shaft rotating at the second position are received in a receiving space of the grinding tub.
